I did turn on all my faucets and outside hose about 1/3. I turned on the main until it started to hammer. I kept it there, thinking that the hammering would resolve itself. I waited at least 15 minutes, but it never went away, sometimes less, sometimes more. Eventually I turned it up, and kept turning it up, until the hammering disappeared and I could continue opening the valve all the way. So I guess with the valve open just a little, there was a region of hammering. | |
